To all it mdyccncem: Be, it known that I, JOHN KIZER LEEDY, a

citizen'ofthe United States, residing. at Roan:

. oke, inthe county of Roanoke and State of Virginia, have invented a new and usefulRail- "road-SignaLfof which the following is a'specification.

' The object of the present invention is to pro- :vide an improved signaling's'ystem for use in reconnection with railway-lines; and it consists principally'inprovidingv a continuous series r ot-signals placed along the. line of the road and visible to all. persons on the train, so that 'the train crew and passengers will be im'me- '15 dihtely informed of the presence of another train-on the same track as well as. thedirection in whichlsaid train .is traveling.-

'With this and otherobjectsin view the jin-' 1 lyention consists in thenovel construction and l arrangement of. parts hereinafterdescribed, illustrated "in the accompanying drawings,

a .andfparticularly pointed out in the appendedclaim,- it :being understood that various changes inthehform, proportions, size, and

2 5' minorizletailsdf the 'structure-' may, be made withoutdeparting from thespirit or sacrificing i'any of the advantages :of-the invention.

'- Inthei'accompanyihg;clrawings,-Figure 1 is I 1; an "elevation, partly in the Inature;of a dia- I 3 gram, illustrating'a railway'signaling system '-con structed arranged inaccordance with my invention; Fig.-' 2 is a side elevation,

1 drawn toan enlarged scale, of a. pair-of oppositely-facing signaling members forming a At regular inte graph-posts being used for the purpose when available. v On each of the posts are secured av block, and in each stationare arrangedqarrows corresponding-to those on the-road and bean,

49 1 numb er of horizontally-disposed bars 2,.placed -one: above the, other andpreferablyin the form .ofarrows having distinct heads, one pointing in {one direction andthe other. in theopposite direction. Thisequipment-is used fora single: trackrailwaywhere trains are moved in both directions, or it may constitute the equipment of a double-trackroad where trains travel 7 inf butone direction on eachtrack. Where three or four or more tracks are employedya corre- 5 sponding-ihumber of arrows are;used,:thear- .color and are'of a numben corresponding to cated at 11, and the ends of'thewires being an; at; the linger. therailroad are placed posts 1,; the ordinary tele'ypole of the.,. battery" anti-the oppositef'poleher j dependent switch, as indicated'ath' i 6 to which. they belong. v On each of the arrows 'arearranged aplurality ofsignaling devices,

which may be of the character illustrated in Fig. 2,; said signaling devices being arranged 'near the heads of the arrows, so that they may be readily distinguished. The signaling devices maybeof the same or of different.

the number-of jtrains which areallowed on a given sectionof theroad at one time. .Genjerally not more'than three trains will' be allowed on, any one section ,or' block, and I have therefore 'illustratedthre signaling devices o'n eacharrow, although the number may be increased or diminished without departing from the invention.- For each signaling device I employ a separate current' conduct ing wire, and in the present instance six' of such wires are employed, as indicated at' 5, 6, 7, 8,-

' 9, and 10 in "the drawings, the-wiresextending from station to station and connected to a 7 suitable source of electrical energy, as indi-' '75 grounded to'estab'lish circuits. All of the first signals of the upper arrows, as indicated at 12,

are connected in series with the ,line -wirel 5.'

The second set of signals 13ers: all :connected in serieswith the. line-wire 6,*and the third. set of signals 14 are connected in series-with the line:wire 7. .On the lower arrows thesig nal's 15, 16, and 17 are connected, respectively,

to the current-conducting wires 8, 9, and 10,

so that when anyone of the current-conduct 35* ing wires is connected withit'he source of elec? trical energy all ofjthe signals along the line connectedto said jvire willbe energized." 3 I A and B are stationszformingjthe ends of a.

jnectedto the line-wires,l the ends of. the wires being connected together and'coupledkto-onei'nggrounded. In thef'station A, which-may be termed the sending station foitftrans j mitting' signals to the upper set-of each of theline-wiresis provided wi said switches being normally open until a train enters the block or section traveling yin'ithe direction indicated by the lower arrows. ,The station operator then closes the switch 5"and' connects the line-wire 5 with the battery,,energizing the signals 12 along the whole of the block or section and signaling to both the'traincrew and passengers. Should a second train enter the block in the same direction, the traincrew of the second train will be immediately informed of the presence of .the preceding train, while the operator will close the switch 6', causing all of the signaling devices 13 to.

controlling the circuits through the line-wires 8, 9, and 10 and the signals on the lower arrows to which said wires are connected,

while at station A these wires are grounded to complete the circuit. Shoulda train leave station B traveling in the .direction of station A, the operator at station the switch 8", energizing all the signals 15 and notifying. all trains on the block traveling in the same or in an opposite direction of the entry of the train leaving station B, and in this manner both' thetrain-crew and the passengers are kept informed as to'the movements and location of trains, and the safety of the train is not wholly dependent on the firemen and engineer. p

The signals are of any desired'construction capable of being'operated by an electric current; but preferably I employ-incandescent lights, which are connected in series as described, the lights being visible for a long distance. The signals are all protected by hoods or bells 20, as shown more clearlyin B. would close same or of different color; but preferably the signals 12, 13, and 14 are of a color distinct from the signals 15, 16, and 17 so that there will be no confusion in the reading of signals displayed by the different arrows.

In order to clearly distinguish the wires be- Fig. 2. The signals displayed may be of the longing to different signals, the three wires of each set are preferably provided with Wrappings of different coloras, for instance, red, white, and twisting, and the cable thus formed may be provided with a'wrapping of'a color different from that of similar cables containing wires belonging to a different set of signals;

Having thus described iny invention, what I claim is. p Arailway signaling system comprising supporting'wposts, a plurality of superposed ar blue -these being assembled by I rows secured at an intermediate point to the I posts and pointing respectively in opposite rections,a plurality of signaling-lamps secured to the arrows between the points thereof and the point of attachment of. the arrows to the posts, the signaling-lamps carried by one ar-' row being of a colordifi'erent from the lamps carried by an adjacent arrow, current-conducting wires connecting corresponding sig nals in series and extending between-two separated terminal points or stations, a source of 1 electrical energy disposed at each station and multiple connection with all of the current-c0nduct0rs a plurality of independent having switches disposed at one station for closing the circuit through the s'ignalscarried by one set of arrows, and corresponding switches dis-- a posed atthe opposite terminal or station for through the signals car-.,

ried by'the second set of arrows.

closing the circuits In testimony that I claim theforegoing as my own I have hereto aflixed my signature in the presence of two witnesses.
